1,4-Diketo-3,6-di(3-cyanophenyl)pyrrolo(3,4-c)pyrrole

The main application fields of 1% 2C4-diketone-3% 2C6-bis (3-hydroxybenzyl) pyrido (3% 2C4-c) pyridine are as follows:
First, in the field of dyeing. This compound has a unique chemical structure, or can give fabrics a specific color and fastness. In ancient times, dyeing relied on natural dyes, but the durability and richness of color were limited. If this material is used for dyeing, it may expand the color range and make the fabric color not easy to fade. For example, the "Zhang Shi" article of "Tiangong Kaiwu" describes the method of dyeing in detail. This material may be a novel agent among them, providing different options for dyeing workshop craftsmen to dye more gorgeous and durable fabrics.
Second, in medicine. Although there was no modern precision analysis technology in ancient times, there were many explorations on the medicinal value of natural and synthetic substances. The special structure of this compound may contain antibacterial, anti-inflammatory and other effects. The ancients often used herbs, trees and gold stones as medicine for treating diseases. If this substance can be found for medicinal purposes, it may add new members to the medical treasure house. Although "Tiangong Kaiwu" does not directly discuss medicine, it is based on the spirit of ancient people's exploration of various substances. It may have potential applications in folk medicine practice.
Third, in the field of material manufacturing. In the production of buildings, utensils, etc., the durability and stability of materials are crucial. This compound may be used as an additive to improve material properties. For example, "Pottery" and "Metallurgical Casting" in "Tiangong Kaiwu" involve ceramics, metal casting and other processes. Adding this material may improve the quality of the material and make the utensils more durable and less prone to damage over time.

To prepare 1,4-diol-3,6-bis (3-benzylphenyl) alkynes and (3,4-c) alkynes, there are many methods for their synthesis, which are described in ancient methods.
First, the molecules can be gradually constructed from suitable starting materials through clever steps. If a specific reaction is first used, a substrate containing a 1,4-diol structure is reacted with a suitable reagent to introduce a specific functional group, which is the basis for the subsequent construction of di (3-benzylphenyl) alkynes and (3,4-c) alkynes.
In one method, 1,4-diol can be substituted with an active halide under mild conditions to form a halogenated 1,4-diol derivative. After that, the derivative is used to couple with the alkynide containing benzylphenyl group under the action of a suitable catalyst and base. This catalyst can be a palladium-based catalyst, and the base can be selected from potassium carbonate. In a suitable solvent, such as dichloromethane or toluene, it is heated to a suitable temperature to make the two coupling efficiently and gradually form the required complex structure. < Br >
Another method can first construct a partial structure of di (3-benzylphenyl) alkynes, and then react with 1,4-diol related intermediates. First, benzylbenzene and acetylene derivatives are reacted through suitable reactions, such as metal-catalyzed addition reactions, to form di (3-benzylphenyl) alkynes. Then, this structure is reacted with specially treated 1,4-diol intermediates under specific conditions, or by means of condensation reactions, the two are connected and the structure of (3,4-c) alkynes is constructed. During the reaction process, the reaction conditions need to be carefully adjusted to ensure the smooth progress of the reaction and improve the yield of the target product. < Br >
Synthesis of this compound requires precise control of the conditions of each step of the reaction, from the selection of reagents, the amount of catalyst, to the control of reaction temperature and time, all of which are related to success or failure. It is necessary to be careful before obtaining this complex 1,4-diol-3,6-bis (3-benzylphenyl) alkyno (3,4-c) alkynyl product.

The physicochemical properties of 1% 2C4-diketone-3% 2C6-di (3-formylphenyl) pyrido (3% 2C4-c) pyridine are as follows:
This compound contains multiple specific functional groups, and the dione structure makes it have certain reactivity. The di (3-formylphenyl) pyrido (3% 2C4-c) pyridine part endows it with a unique electronic structure and spatial configuration.
From the perspective of physical properties, due to the relatively large size and complex structure of the molecule, it is speculated that its melting point is higher. There is a conjugated system in the molecule, or it is absorbed at a specific wavelength and shows a certain color. Contains polar functional groups and has a certain solubility in some polar solvents such as dimethyl sulfoxide, N, N-dimethylformamide.
Chemically, the carbonyl group of diketone can undergo nucleophilic addition reactions, such as reacting with alcohols to form ketals and reacting with amines to form imines. Formalyl groups can participate in a variety of classical organic reactions, such as hydroxyaldehyde condensation reactions, which can further construct complex structures. Pyridine ring is basic and can form salts with acids, changing its solubility and reactivity. The conjugated system makes the molecule have a certain electron delocalization, and under appropriate conditions can participate in the electron transfer process or undergo photochemical reactions. These physicochemical properties make it potentially valuable in materials science, organic synthesis, and other fields, and can be used to prepare functional materials or as intermediates to synthesize more complex organic compounds.

The question involves the price range of the item, which mentions the market price of "1,4-mitral-3,6-bis (3-benzylphenyl) piperazine and (3,4-c) piperazine". However, the items mentioned here, or the medical device "mitral valve" and the chemical "bis (3-benzylphenyl) piperazine and (3,4-c) piperazine", are unusual things.
The mitral valve is an important structure of the heart. In the medical market, the price of artificial mitral valve varies greatly. Ordinary mechanical mitral valve, the price may range from a few thousand yuan to more than ten thousand yuan; while biological mitral valve, because of its material and production process, the price can reach tens of thousands of yuan. The price range is determined by factors such as brand, material, production process and market supply and demand.
As for "di (3-benzylphenyl) piperazino (3,4-c) piperazine", this is a chemical compound, which is mostly used in scientific research, pharmaceuticals and other fields. Its price varies depending on purity, output and market demand. For high purity, if used in precision scientific research, the price per gram may reach several hundred yuan or even higher; for mass production and slightly lower purity requirements, the price may be relatively low, tens of yuan per gram may also be possible.
Overall, the price range of the mitral valve ranges from thousands to tens of thousands of yuan; the price per gram of "bis (3-benzylphenyl) piperazine (3,4-c) piperazine" ranges from tens to hundreds of yuan, and the specific price still depends on the actual market conditions.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. However, the content of the inquiry "Manufacturers of 1,4-diol-3,6-bis (3-hydroxypropyl) piperazino (3,4-c) piperazine" is not related to the production of this modern chemical substance. Gai "Tiangong Kaiwu" was formed in ancient times, when the chemical industry was not flourishing. The production and manufacture of these fine organic compounds was far beyond the level of science and technology at that time.
"Tiangong Kaiwu" details ancient agricultural and handicraft technologies, such as grain cultivation, textiles, salt making, smelting, ceramics, etc. It has detailed records of the selection of raw materials, production processes, and tool use in various industries, reflecting the highly developed production skills of ancient China. However, modern chemical synthesis of 1,4-diol-3,6-bis (3-hydroxypropyl) piperazino (3,4-c) piperazine requires modern chemical synthesis methods, professional equipment and advanced technology, which is very different from ancient production technology.
If you want to find a manufacturer of this compound, you can consult a professional in the chemical industry or a relevant scientific research institution in the modern chemical industry information, chemical product catalog, professional chemical website or industry exhibition materials.
